CXTShellTreeBase::OnDeleteTreeItem

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

We are using XtremeToolkitPro library. We currently upgraded from 9.81 to 10.3.1, I noticed that a new function is added:

In xtshelltreebase.coo: CXTShellTreeBase::OnDeleteTreeItem. 

It is giving us a crash at this particular position. I noted that inside this function you are assuming that lParam to be 

XT_TVITEMDATA* lptvid, where as we are using it for our internal purposes. Is there a way to avoid this function being called when I call DeleteAllItems.
Kindly help,
Regards,
Sachin Modak.

	Hi, I don't believe that in 9.81 you use lParam and it worked. All code of CXTShellTreeBase assumes that lParam is XT_TVITEMDATA For example check OnFolderExpanding - how it will work if lParam not XT_TVITEMDATA.

	We have not changed that part of code which you are referring to. My question is more of a wonder as to what would happen if you add that particular message map inside CXTShellTreeBase::OnDeleteTreeItem(). I compared the CXTShellTreeBase classes from 9.8.1 and 10.3.1 and figured that you added a new handler or was it moved from some other class? This part of code has definately changed file: "c:\program files\codejock software\mfc\xtreme toolkitpro v10.3.1\source\controls\xtshelltreebase.cpp" In the mean time I am looking at OnFolderExpanding. BTW this happens when i call m_treeItms.DeleteAllItems(); in our code. Thanks.

	I observed that in OnItemExpanding for our tree, we have overridden your message handler. I did the same for OnDeletetreeItem and that fixed the problem. Thanks. Sachin Modak.
